[AMPS] SB-220 Smoke Test

[A P]

First. . .good news Jose. Just keep up the high voltage respect . . .

Second. . . SB-220 with directly grounded grid (three rg58 braids on each
tube). Smoke test was a complete success. The amp tuned up on all bands
(though with more load capacitance than expected into the dummy load) and
put out rated power. For 70W input on 28.885 it put out 900W (120VAC mains).
Tuning was smooth and all functions were as expected. I think I'm going to
leave the amp this way. . .

Thanks to all for the advice . . . .
